What is the total number of valence electrons in all the atoms in li3n?

Li3N is lithium nitride, an ionic compound. Lithium, being an alkali metal, has 1 valence electron. The "3" subscript means there are 3 of them. Nitrogen is a non-metal with 5 valence electrons. This means it needs 3 more to satisfy the octet rule, which it gets from the 3 lithiums. So, nitrogen's 5 plus lithium's 1 (times 3) = a total of 8 valence electrons.

The valance electron of N is 5 while valance electrone is 1 then Li3N valance electrone is 6 electrone

What is the total number of valence electrons in oxygen?
The answer is not 6 as said here before! The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons. 6 of them from each oxygen (O) atom. 4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each. I hope there is some help in this.
Is the number of valence electrons equal to the number of protons?
No, the number of total electrons is equal to the number of protons.
How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
What is the total number of valence electrons in an atom of nitrogen in the ground state?
A fluorine atom in the ground state has 7 valence electrons.
What is the total number of valence electrons in a fluorine atom you n the ground state?
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
Is it true that to find the total number of electrons available for bonding in a positive ion you should add the ion charge to the total number of valence electrons of the atoms present?
yes
How many total valence electrons take part in triple bond between 2 atoms?

What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
How does the number of valence electrons change?
There is no simple answer to your question, as your question is too broad and undefined. For simple atoms, the number of valence electrons is the number of electrons in unfilled electron shells, which are then available for bonding to another atom. Oxygen with 8 total electrons has 6 paired electrons in filled electron orbitals, and 2 valence electrons in unfilled orbitals. That is why it forms bonds with 2 hydrogen molecules to form water (H2O) The number of valence electrons can change when you add or remove electrons from an atom, or in more complex atoms where filled orbitals to unfilled orbitals have the same energy and electrons can move from one to another depending on the number of other atoms it is binding with.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
How many electrons does hydrochloric acid have?
Valence electrons are the electrons from the outermost shell of the atom. Number of valence electrons in an atom = the group number of that atom Valence electrons of a moleucle = sum of the valence electrons of all the atoms in that molecule. The molecule HCl has 1 hydrogen (group number =1) and 1 chlorine atom (group number =7). The total number of valence electrons in HCl = 1(1) + 1(7) = 8 Pushpa Padmanabhan Lansing Community College
What is the number of shared pairs of electrons in C6H14?
30 valence electrons. Valence electrons are on the outer shell of a atom. To find valence electrons, subtract the amount of electrons the noble gas has before the element from the number of electrons the element actually has. Since the noble gas before carbon is Helium, you subtract 2 electrons from 6 electrons which gives you 4 valence electrons. Since there are 6 carbon atoms, multiply 4 by 6 to get 24. Do the same to the hydrogen atoms and add the valence electrons of the two molecules together and you should get 30 total valence electrons.
What is the total number of valence electrons in oxygen?
The answer is not 6 as said here before! The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons. 6 of them from each oxygen (O) atom. 4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each.

What is the number of electrons in the valence shell of an atom of aluminum in the ground state?
2 valence electrons are in an aluminum atom in the ground state.
